Propeller guard and unmanned aerial vehicle

An inspection apparatus () according to an aspect of the present invention includes a first determination unit () that determines an operation of an unmanned aerial vehicle () based on a first threshold for determining whether the unmanned aerial vehicle () can enter the inside, a second threshold, which is greater than the first threshold, for determining whether the unmanned aerial vehicle () can land on a water surface of pooled water in the inside, and space information indicating a space of the inside, and a second determination unit () that determines a flight altitude of the unmanned aerial vehicle () with respect to the water surface or a floor surface of the manhole after the unmanned aerial vehicle () enters the inside based on the first and second thresholds, and the space information in a case where it has been determined that the unmanned aerial vehicle () can enter the inside and cannot land on the water surface.

Inspection device, inspection method, and program

The present invention provides a glass plate module to be attached to a vehicle. The glass plate module includes laminated glass in which an outer glass plate, an interlayer, and an inner glass plate are layered in this order; a mask layer that is provided on the laminated glass and blocks a field of vision from outside; and an attachment member that is attached to a portion corresponding to the mask layer on the inner glass plate with at least a first adhesion means and a second adhesion means and configured to support an information acquisition device for acquiring information from outside of a vehicle. The first adhesion means includes adhesive at at least one location. The second adhesion means is configured such that the adhesive conducts preliminary fixing prior to curing. The attachment member includes a fixation portion that faces the mask layer and has a bonding surface provided with the adhesion means. The fixation portion includes at least one adhesive confirmation portion through which the adhesive applied to the bonding surface can be seen from the vehicle interior side.

A technology for creating an arbitrary viewpoint image with high quality based on pixel value information as seen from a single viewpoint and real spatial positional information has not been known. A hidden point is extracted based on a relative positional relationship between a single viewpoint closed surface projection point for arbitrary measurement point and neighboring projection point, a relative positional relationship between other viewpoint closed surface projection point for arbitrary measurement point and neighboring projection point, distance from arbitrary measurement point to another viewpoint, and distance from measurement point projected onto neighboring projection point on the other viewpoint closed surface to another viewpoint. Furthermore, the projection point pixel value on the other viewpoint closed surface for the extracted hidden point is corrected using distance from measurement point projected onto neighboring projection point on the other viewpoint closed surface to the other viewpoint and the measurement point pixel value.

Other viewpoint closed surface image pixel value correction device, method of correcting other viewpoint closed surface image pixel value, user position information output device, method of outputting user position information

A sheet member with a frame body in the present invention has the sheet member and the frame body composed of a resin material attached to a fringe of the sheet member, wherein the frame body opens in an outward direction parallel with a sheet face of the sheet member and in the frame body a fit-in groove is formed to fit in a fit-in object, and wherein the fit-in groove is formed so as to have an overlap space with the sheet member in a direction parallel with the sheet face of the sheet member.
